Title: Process for the preparation of contact lens having a good oxygen permeability and using fluoro alkyl monomer
Inventor: KIM KWANG-UNG
IPC: C08F30/08
Filed: 1992-10-29
Granted: 1995-09-12
Abstract: The fluoroalkyl contg. monomer is prepd. by reacting fluoroalkyl carboxylic acid or fluoroalkyl carboxyl halide or fluoroalkyl sulfonic acid or fluoroalkyl sulfonyl halide, with the acrylic monomer comprising hydroxyl gp. and amine gp., or the styrenic monomer comprising hydroxyl gp. or amine gp., or the vinylether type monomer. The polymer usful for preparing a contact lens having good oxygen permeability is prepd. by (co)polymerising 5-100 wt.% of the obtd. fluoroalkyl contg. monomer, 0-60 wt.% of silicone contg. monomer, 0-60 wt.% of vinyl based monomer, 0-10 wt.% of crosslinking monomer, and/or 0-5 wt.% of hydrophilic monomer.
Patent KR-100237950-B1 (KR)
Title: Glass substrate coated with a low emissivity coating and method thereof
Inventor: ZAGDOUN GEORGES M
IPC: C03C27/06
Filed: 1992-11-24
Granted: 2000-01-15
Abstract: Glass substrate provided with a low-emission, conductive, transparent functional layer based on metal oxide(s), on which an "outer" coating is deposited whose optical thickness is approximately one quarter of the average wavelength belonging to the visible range, and preferably centred on 550 nm. In addition, an "inner" coating is provided between functional layer and substrate, the said coating having an optical thickness of between 50 and 75 nm.

Abstract: 본 발명은 일반적인 형태의 연료 분사 밸브의 기능과 조정 정확도를 개선하고 제작 비용을 줄이는 것을 목적으로 한다. 
     본 발명은 스파크 점화 엔진용 전자기 작동 연료 밸브(1)의 경우에 노즐(5)의 출구 개구(9)와 밸브 시이트(8)과 가이드 트랙(14)서로에 대해서 매우 높은 정확한 배열을 이루므로써, 분리 가이드 링(7)이 용접 연결부(2)에 의해 길이 방향 홀(13)내에 일정한 방사 거리로 유지되어 있는 연료 분사 밸브의 기능 정확도와 마모거동을 개선한다. 본 발명은 특히 차량 엔진용 연료 분사 밸브에 사용된다.
